Focal Diva Utopia Wireless Streaming Active Loudspeaker

What if there was a character in Stanley Kubrick's classic movie 2001: A Space Odyssey who was an audiophile? Aboard the Discovery One interplanetary space ship, what would his system look like? He'd probably have a pair of ultramodern speakers that could pluck sound out of the ether. He'd control the system with something like a present-day smartphone or tablet, commanding the HAL 9000 computer to play his favorite songs. The speakers would stand unobtrusively in a white room with 1970s modern-minimalist furniture, no rack of components to drive them, no wires connecting them, no shelves of physical media to play. And they would fill the room with music.

I am sitting earthbound in my living room almost a quarter-century beyond the year 2001, living a similar scenario with the Focal Diva Utopia streaming amplified wireless speaker system. My living room is not at all reminiscent of the Discovery One with its rotating central interior (footnote 1). But with the Diva Utopia system, I feel more in a sci-fi future young me might have imagined than with any hi-fi component I've reviewed so far. About the only thing the Diva Utopia has in common with the stereo systems I grew up with—and with my current reference system—is two floorstanding cabinets and diaphragms that move air to make sound.

Aurorasound HFSA-01 integrated amplifier

Audiophiles are often misunderstood as mere hobbyists; in fact they hold a profound reverence for sound. Japanese jazz kissas, where vintage vinyl, turntables, tube amplifiers, and horn speakers have drawn audiences since the 1950s, exemplify this passion. Western audiophiles share a similar fervor, though our pursuit of sonic perfection often manifests in a more discreet, almost monastic, lifestyle.

Shinobu Karaki, a 65-year-old electronics designer, is the founder and chief designer of Japan's Aurorasound. A music lover first, an audiophile second, and an aspiring jazz and classical guitarist, Karaki crafts phono stages, step-up transformers, preamplifiers, power amplifiers, and integrated amplifiers for his Yokohama-based audio company.

Gramophone Dreams #94: Sparkler Audio S515t CD transport, Beyerdynamic DT 1990 PRO MKII and DT 1770 PRO MKII headphones

I am a lucky person. I've been writing monthly audio columns since 1992, and the chief benefit of that privilege has been that each month my mind is free to visit distant shores searching for exotic artifacts that readers might never encounter at their local audio emporium. This month, my raft drifted again onto Japan's metaphorical shores.

I was cordially greeted by an international cohort: Victor Kung (VK Music in Canada), Yoshi Segoshi (the American distributor for 47 Labs), Junji Kimura (47 Labs' founder and chief engineer), and Kazutoshi Tsukahara, formerly associated with 47 Labs (in Japan) and now founder and chief engineer of Sparkler Audio, which is also based in Japan. Sparkler Audio makes modestly priced components including the model S515t "ballade II" CD transport, which I am about to describe.

Spin Doctor #22: Cleaning LPs and the HumminGuru NOVA HG05

The first album I ever bought with my own money—cash earned mowing neighbors' lawns—was a British plum-label pressing of Led Zeppelin II. It was 1971. I rode my prized Raleigh Chopper bike from our home on the coast of Denmark down the road a couple of miles to the local record store in a small town called Hørsholm.

After entering the store and browsing for a few minutes, I mustered up sufficient courage to head to the counter with the second Zeppelin LP and ask to listen to it. All was musical bliss for a few minutes. Then just as I was really getting into it, about halfway through "What Is and What Should Never Be," the clerk decided I'd heard enough and rudely interrupted my listening session with a "get lost kid" look on his face. I surprised him by pulling out my lawn-mowing cash and buying the album. I pedaled home furiously, as fast as I could, and slapped my first LP onto the family Garrard Autoslim, which I wrote about in Spin Doctor #11.
